摘要
通过对北京市典型居民用户全年天然气温度的采集和分析,提出燃气有效日平均温度概念,得到全年用户燃气温度的变化规律。给出居民用户无温压补偿带来的全年计量相对误差计算公式,计算得到由于无温压补偿带来的年计量相对误差为-3.4%。通过经济性分析,建议城区新建或到期更换的居民用户可安装具有温压补偿功能的燃气表。
Through the collection and analysis of annual natural gas temperatures for typical residen- tial natural gas users, the concept of the effective daily average temperature of natural gas is proposed, and the change rule of annual natural gas temperatures for typi cal residential users is obtained. The calculation formula of the annual metering relative error without the temperature and pressure compensation for residential natural gas users is presented, and the annual metering relative error without the temperature and pressure compensation is -3.4%. Through the economy analysis, it is suggested that gas meters with the temperature and pressure compensation can be installed by new residential users or users to replace their meters that are expired.
